That suggests to me that shooting for charge currents in the tens of mA will be dicey at best. The Hackaday Prize.


What do you think? Fortunately LiRs are affordable enough that you can afford to kill a few. TP should be fine to charge a LiPo.

Using the max rate of mA with ohms, one can do the following:. It depends on the brand. By using our website and services, you expressly agree to the placement of our performance, functionality and advertising cookies.

With that formula, 33k would give about 36mA. Sure, coin cells usually last a long time — but do you really want to buy new ones and throw the datahseet ones out? Now what if you added a few resistors and a dip switch too? Can the micro usb port be used to charge and discharge the cell?
